Question

$\huge \tt \red{answer}$


$\tt{If \: A \: Sin \: 54° = \: Sin \: 1° \: then,}$


a) A < 0

b) A = 0

c) A > 0

d) A = 1

Hint:- Option C is Correct.​

Answer 1

$\purple{ \sf {Given :}}$

$A \sin(54 \degree) = \sin(1 \degree)$

Since $\sin$ is an increasing function, interval $(0,\frac{\pi}{2})$.

$\implies \sin(1 \degree) < \sin(54 \degree)$

Since both $\sin1°$ and $\sin54°$ are POSITIVE.

$\orange{ \therefore A > 0 \:\:(must\:be\:+ve)}$
